I’m embarrassed but will be honest here. I don’t have a snow blower but have a mower and a pressure washer. In the fall I bought an adapter for blowing out water lines on a camper and I hook it to my washer and blow the water out of the pump and lines. I fill up the gas tank to the top and shove it in the corner. The lawn mower I fill the tank up and shove it next to the washer in the corner and then any gas left in the can I dump in the car to use it up. In the spring I pump the bulb about 5 times and it starts on the second pull. The Honda engine on the washer starts on one pull. Not sure if this is good practice or not but it is what I have done for 50 years. My dad always said in the winter keep your tank full and you won’t get water.

I knew an old guy as a kid that had a boat with a V8 inboard engine and every fall he would start it up and slowly pour half a can of marvel mystery oil down the carb revving the engine to keep it running. It would smoke like a bear. After half the can was out he would dump the rest in and stall out the engine. He would tell me now that can sit 50 years if you want and be as good as new. It would start up in the spring and smoke for 15 minutes and then run great all summer.

Your last option...is Cam II , I use it in all my 2 strokes and 4 strokes get a mix of 50/50 with ultra Sunoco.
Never have the issues of tearing apart carbs again.
Those 2 stroke carbs are no fun, its easier to buy a new weedwacker.
